State Highway 15 (SH 15) is a New Zealand state highway in the Northland region of the North Island. It is 126.5km long and links SH 1 with the Marsden Point Oil Refinery and Northport.

History

Prior to 1930, the recommended route by the Automobile Association, from Whangarei to Kaitaia was via Mangakahia and was named Highway 1. Approximately 90 years later a formal designation has been re-instated. The current SH 1 south of Kawakawa was only a rough clay road in the 1920's.^[1] Also known as the Northland Inland Freight Route it was declared a state highway in August 2016. Formerly administered by the Far North District Council and Whangarei District Council, in May 2015 the New Zealand Transport Agency agreed to include it to the state highway network after lobbying from the local authorities and industries given its significance to the regional forestry industry and its connectivity to the regions port near Marsden Point.^[2][3] Of the newly declared state highway, 96km is former council administered roads, 8.5km was from the former SH 15A and the remainder shared as concurrencies with SH 1, SH 12 and SH 14.^[4]

Route

State Highway 15 commences at SH 1 near Okaihau. It follows Te Pua Road for 7.4km before intersecting SH 12 and turns west, where is shares a concurrency for approximately 2km into the town of Kaikohe. SH 15 then turns south at Mangakahia Road where it travels on mostly rural road through forestry, changing orientation from a south to a southeast direction, for approximately 70km where it intersects SH 14. It shares a very brief concurrency with SH 14 and then leaves it to continue southeast on Otaika Valley Road for approximately 10km where it ends at Loop Road where a short connection of the northern part of Loop Road meets SH 1.

From this point SH 15 shares a concurrency with SH 1 southbound for approximately 20km where it arrives at the Ruakaka roundabout. The last 8.5km section of SH 15 is part of the former SH 15A spur which was renamed as part of the new decalaration. This highway travels northeast along Port Marsden Highway for 8.5km, terminating at the entrances of Northport and Marsden Point Oil Refinery. The first 3km of this section of highway runs along the route formerly taken by the southern end of One Tree Point Road, which was significantly realigned as part of its upgrade to highway status. The next 3km of the highway uses a section of road which was newly built as part of the creation of the highway, whilst the final 2.5km uses an existing road which was formerly the northern end of Marsden Point Road.^[5]

Former SH 15A

SH 15A was a former state highway which is now part of the southeastern spur of SH 15 connecting SH 1 near Ruakaka to Marsden Point. For many years 15A was a peculiarity since there wasn't any corresponding SH 15. This is because the original SH 15, which used to connect SH 1 with the former site of Port Whangarei, had its highway designation revoked in December 2003.^[6] SH 15A was created six months later, in June 2004, to provide a highway connection to the new site of the port at Marsden Point.^[7]

Former SH 15

The first designation of SH 15 was declared as a new designation in 1997 however it had its highway status revoked in 2003. SH 15 was 4.5km long and connected State Highway 1 with Port Whangarei.^[8] The highway started at a junction with SH 1 in the suburb of Raumanga, and ran along Rewa Rewa Road, Kioreroa Road and Port Road before terminating at the entrance to Port Whangarei. The route had its highway status revoked in December 2003, as part of the closure of Port Whangarei to commercial shipping and the opening of Northport at Marsden Point. Six months later, in June 2004, SH 15A was gazetted to provide a highway link to the new port facilities at Marsden Point.
